Fix a bug where gimp would crash on startup on -CURRENT because a translated
pointer was being free'd accidentally.

Roll mpeg-lib into the two gimp ports. mpeg-lib is now abandoned ware, and will
be removed from the ports tree soon.
mpeg-lib will now be built solely for the purpose of gimp, and no libmpeg.*
will be installed on the system. This will avoid a namespace conflict with
KDE which also installs a libmpeg.so. These two libraries are incompatible.
